Evaluation of Patient Comfort and Satisfaction After the Construction of Maxillary Obturator Prosthesis for Limited Mouth Opening in Maxillofacial Cases With Different Approaches: Cross Over Randomized Clinical Trial
Evaluation of Patient Comfort and Satisfaction After the Construction of Maxillary Obturator Prosthesis for Limited Mouth Opening in Maxillofacial Cases With Different Approaches: Cross Over Randomized Clinical Trial
A patient's quality of life is frequently negatively impacted by oral cancer, which is a serious condition. Treatment for oral cancer, which includes radiation, chemotherapy, and surgery, can result in several oral complications. The risk of impression material becoming lodged in undercuts and the challenges in retrieving the material would be inconvenient for both the patient and the dentist. Therefore, a digital pathway was chosen for the prosthesis fabrication process So, the present study aims to investigate the patient comfort and satisfaction after the construction of maxillary interim obturator for radiation-induced trismus in maxillofacial cases with different approaches: conventional and digital fabrication processes.
A patient's quality of life is frequently negatively impacted by oral cancer, which is a serious condition. Treatment for oral cancer, which includes radiation, chemotherapy, and surgery, can result in several oral complications, including trismus, xerostomia, dysgeusia, odontogenic infections, and osteoradionecrosis.
Aim: the present study aims to investigate the patient comfort and satisfaction after the construction of maxillary interim obturator for radiation-induced trismus in maxillofacial cases with different approaches: conventional and digital fabrication processes.
Methodology: The present crossover study will be conducted on 30 maxillofacial patients with maxillary defect with limited mouth opening, aged between 50 -65 years, will be selected for the study from the Maxillofacial clinic of the Prosthodontic Department, Faculty of Dentistry, Mansoura University.A preliminary impression of the maxillary defect will be made with a high-viscosity irreversible hydrocolloid, covering all the margins of the defect and blocking all unfavorable undercuts with wet gauge piece.In a simple randomized method, 15 patients will receive obturator fabricated by the digital method.The other 15 patients will receive obturator fabricated by the conventional method Patient comfort and satisfaction by visual analogue scale (VAS), and Gothenburg Trismus Questionnaire (GTQ) at follow-up periods as follows: T0 immediately after insertion of obturator, T1= three months after insertion of obturator, T2=six months after insertion of obturator.
Inclusion Criteria:
Patient with unilateral total maxillectomy.
Free from any signs of inflammation in the defect area. The defect size is large.
Exclusion Criteria:
Patient is still receiving radiation. The defect size is small. Defects result from trauma.
